Free Sony firmware, released today, adds AF support for A-mount lenses when used with the firm?s NEX-5 and NEX-3 cameras.

?Single-shot autofocus is supported with 14 optional A-mount SAM and SSM lens models when used with the optional LA-EA1 Mount Adapter,? said Sony in a statement.

?Single-shot AF is also possible while in movie recording mode by pressing the shutter button halfway down.?

AF support for A-mount lenses also requires a separate firmware upgrade for the LA-EA1 adapter.
